four wheel drive VOLVO S80 2004 Owners Manual

Manual shifting - Geartronic
You can move the gear selector freely between the (MAN) ual and (D)rive positions while driving. Gears 2, 3, and 4
have a "lock -up" function which reduces engine speed and helps save fuel.
The currently selected gear will be displayed in the instrument panel (see page 25
).
To access the (MAN)ual shifting position from (D)rive, pull the gear selector back slightly from D and move it to
the left to MAN.
To return to the (D)rive position from MAN, move the gear selector to the right and push it forward to the (D)rive
position.
While driving
If you select the (MAN)ual position while driving, the gear that was being used in the (D)rive position will also
initially be selected in (MAN)ual position.
Move the gear selector forward (toward "+") to shift to a higher gear or rearward (toward "-") to shift to a lower
gear.
If you hold the gear selector toward "-", the transmission will downshift one gear , and will utilize the braking power
of the engine. If the current speed is too high for using a lower gear, the downshift will not occur until the speed has
decreased enough to allow the lower gear to be used.
If you slow down to a very low speed, the transmission will automatically shift down.
When starting in the (MAN)ual position, 3rd gear is the highest gear that may be selected.
NOTE: Kickdown (see previous page) does not function when the transmission is in the manual shift (geartronic)
mode. The gear selector must be in D (Drive) position.
W Winter/Wet driving mode - enhanced vehicle traction
Mode W will only function if the gear selector is in the (D)rive position.
Press the button at the base of the gear selector to engage/disengage this driving mode (see illustration).
An LED in the button will light up to indicate that W is engaged and this will also be displayed in the instrument
panel (see page 25
).
This mode may be selected for starting/moving off on slippery roads.
pg. 78 Four -C active chassis system
Four-C (option)
Your car can be optionally equipped with the Four-C (Continuously Controlled Chassis Concept) system.
This system is based on a number of sensors that continuously monitor factors such as the car's lateral and vertical
movements, speed, and movements of the wheels. The sensors receive data up to 500 times per second, which is used
to provide extremely fast and precise adjustment of each shock absorber. The system adjusts the stiffness of the shock
absorbers approximately 100 times per second.

Snow tires, studded tires *
Tires for winter use:
Owners who live in or regularly commute through areas with sustained periods of snow or icy driving
conditions are strongly advised to fit suitable winter tires to help retain the highest degree of traction.
It is important to install winter tires on all four wheels to help retain traction during cornering, braking, and
accelerating. Failure to do so could reduce traction to an unsafe level or adversely affect handling. Do not mix tires of
different design as this could also negatively affect overall tire road grip.
Volvo recommends 215/55 R16 winter tires on all four wheels .
Winter tires wear more quickly on dry roads in warm weather. They should be removed when the winter driving
season has ended.
Studded tires should be run-in 300-600 miles (500-1000 km) during which the car should be driven as smoothly as
possible to give the studs the opportunity to seat properly in the tires. The tires should have the same rotational
direction throughout their entire lifetime. In other words, if you wish to rotate the wheels, make sure that the same
wheels are always on the same side of the car.
NOTE: Please consult state or provincial regulations restricting the use of studded winter tires before installing such
tires.
* Where permitted.
pg. 96 Wheels and tires
Tire pressure label
Checking and correcting tire pressure
Check the tire pressure regularly.
The tire pressure should be corrected only when the tires are cold.
With warm tires, correct only when the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label located on the inside of the fuel filler door*. This label lists both tire and vehicle design limits. Do
not load your car beyond the indicated limits.
